Text Solution

Verified by Experts

When d-electrons absorbs energy from visible region they will get excited. Absorbed energy is related to a particular wavelength.
`underset("absorbed")(E (triangle))=(hc)/(lambda_("absorbed"))`
When electrons fall into lower energy level it will show whose wavelength `(lambda)` is the complimentary of absorbed wavelength `(lambda_("absorbed"))`
